The broker trying to sell the historic Cannon Building in Troy believes he could have an offer on the property by the end of the month.

Developer Sandy Horowitz put the five-story, 55,000-square-foot building on the market over the summer. It is currently listed for $3.15 million.

Horowitz, who grew up on Long Island but spent much of his career in Hollywood making low-budget horror and science fiction films, started buying up historic buildings and industrial properties in Troy about 10 years ago to cash in on a hoped-for resurgence of the city's downtown.

But Horowitz ran into trouble with his creditors following the 2008 financial meltdown and filed for Chapter 11 bankruptcy in 2010 in California, once his legal residence. He now lives in Montana.

The Cannon Building, which was built in 1834 and is listed on the National Register of Historic Places, is currently being used by Horowitz as an extended-stay hotel and has retail space on the ground floor.

Horowitz has been asking the California judge overseeing the case for more time to pay off his creditors before the case is converted to a Chapter 7 liquidation that would force him to auction off his real estate holdings.

In a recent court filing, John Burke of Select Sotheby's International Realty of Saratoga Springs said he has shown the Cannon Building to five potential buyers, and one has expressed interest in making an offer by the end of the month. A second prospect recently came forward with serious interest, Burke said.

On Thursday, Burke said he has heard from investors in the Capital Region, the New York City area and New Jersey.

"It's such a beautiful building of tremendous importance," he said.

Burke said those who have examined the building believe it could be a multifamily apartment building; others like the extended-stay hotel use, which Burke said produces a very good revenue stream.
